Double-raft type new energy equipment for preparing fresh water by utilizing wave energy

The invention discloses double-raft type new energy equipment for preparing fresh water by utilizing wave energy, and belongs to the technical field of new energy. The raft comprises a front raft body and a rear raft body, and the front raft body and the rear raft body are connected through a double-raft-body connecting hinge mechanism. A high-pressure gas storage tank, a gas-liquid booster pump, a reverse osmosis membrane assembly and a water storage tank are arranged in the front raft body, and a heat exchanger is arranged in the high-pressure gas storage tank; an air cylinder assembly is arranged between the front raft body and the rear raft body and connected with the rear raft body in a hinged mode. Wave energy is received through the front raft body and the rear raft body, the piston rod piece and the raft bodies are connected through the piston connecting hinge, the piston connecting hinge moves to drive the piston to conduct air inlet and exhaust processes, the wave energy is converted into reciprocat
